In our paper we presented relative risks (risk ratios) for HLA alleles that had low p-values in the case-control association analysis. However, our samples were selected on the basis of disorder status, and, therefore, a more appropriate way for assessing the strength of association would have been provided by odds ratios. We would therefore like to report the odds ratios for those five HLA alleles, as estimated using the same data used in the estimation of the relative risks: DR10 8.085; DQA1*0301 0.674; B57 0.449; DR4 0.599; DR12 0.255. Please note that this does not affect the conclusions of the study, as the observed odds and risk ratios are in the same direction.
